In the Supabase Swift SDK 2.x, .select() returns a PostgrestTransformBuilder and is synchronous. The filter methods (.eq, .in, .gt, etc.) live on the PostgrestQueryBuilder returned by .from(), so they must come BEFORE .select(). Only .execute() is async throws. A misplaced try await and unreachable catch errors are almost always a symptom of a method that didn't match the chain.
